Embodiment Construction

[0016] First select the cable barrel 8 with a barrel length of 80mm, weld it on the bulkhead 6 where the cable 9 needs to pass through, and remove the garbage and oil stains in the cable barrel 8. In order to reliably ground the shielding layer of the cable, if the cable has an outer sheath, it is necessary to strip a 40mm long section of the sheath from the surface of the cable 9 passing through the cable barrel 8. The position where the sheath should be stripped is located at one end of the cable barrel 8 At the depth of 20mm of the barrel mouth, in order to minimize the grounding resistance, tin-weld the ground wire 1 on the outer shield of each cable 9 stripped of the sheath, and connect them to the grounding bolt 3 at the outer port of the cable barrel 8. Pay attention to be careful when stripping the sheath, and must not damage its shielding. When multiple cables run through, the exposed section of the cable should be neat; pay attention not to pull the cable too tightly ...

Abstract

The invention features the following: using metallic filament ball to fill the gap between cables or between cable and bulkhead, and filling the conducting daub and sealant at both side of the metallic filament ball; and further, the cable, conducting daub, sealant and metallic filament are loaded together into a cable pipe, and the cable pipe passes through the bulkhead and makes a sealed connection with the bulkhead.

Description

technical field [0001] The invention belongs to the field of electromagnetic compatibility, and more specifically relates to an electromagnetic shielding compartment cable penetrating technology. Background technique [0002] Due to the continuous development of electronic and electrical products, the number and scope of electronic and electrical products are rapidly expanding. Electromagnetic compatibility of electronic products, electronic equipment and electrical systems has become a very prominent issue. If the electromagnetic compatibility problem is not solved well, the operation of the equipment will be disturbed, or it will not work normally at all, and the equipment will even be damaged. Especially for the environment with narrow space and many equipments, such as telecommunication control room, computer room, ship control room, etc., electromagnetic compatibility work is a matter of life and death, which must be considered in advance during design, installation an...
